COCKROACH-TRAP.

Specification of Letters Patent.

Application filed July 13, 1910.

Serial No. 571,319.

To all whom it may concern: I

Be it known that I, ALBERT A. BoRKnN- HAGEN, a citizen of the UnitedStates, residing at St. Louis, in the State of Missouri, have inventedcertain new and useful Improvements in cockroach-Traps, of which thefollowing is a specification.

This invention relates to that class of traps which are used forcatching cockroaches and other similar insects.

It is my object to provide a simple, cheap and efficient trap which canbe easily emptied, cleaned and baited.

In the drawings, which are to be taken as a part of this specification,I show an embodiment of my invention in a preferred form.

Figure 1 is a perspective of my trap; Fig. 2 is a cross section throughthe center of Fig. 1.

The body of the trap A is preferably constructed of wire netting, asshown in the illustrations, with metal top B, bottom G and wire-nettinginlet D. It may, however, be constructed entirely of metal, or of anyother suitable material.

The construction of this trap has many novel features. The entrance Dpasses through an aperture in the body portion A, so that it can easilybe removed. This apert-ure may be faced with metal F so as to be strongand durable. The large end of the tapered-tube-shaped entrance member Dis provided with a broadened portion at the mouth, which gives more roomfor the insects to enter, and prevents the entrance from rolling orturning. At the small end of the entrance, the rough wires are leftpointing inwardly. This makes it impossible for an insect once in thetrap to get out. Along the bottom of this entrance, I provide a strip ofbait, the entire length. In the drawings, this baiting means is shown asa strip of bait absorbent material G such as felt, fastened in asuitable manner, such as by hooks G to either end of the entrance. Anyother means of providing a strip of bait may be employed, however. Thecover B is also provided with bait, as shown at E.

As shown in Fig. 1, the cover is provided 7 with L-shaped slots H, whichlook it to the body portion by simply pushing down the cover over theoutstanding rivetsand slightly rotating. The cover so constructed allowsthe trap to be carried by the handle without danger of the coverslipping off. The bottom C may or may not be detachable. In the drawingsit is shown riveted to the base of the netting by rivets C Theadvantages my invention has over others are marked. The bait can berenewed by removing the cover and entrance without moving the entiretrap. The insect scents the bait much more quickly in this trap than inothers, for the bait G extends all along the entrance and is much closerto the insects outside of the trap than in traps heretofore used. Theparts being separable can be easily cleaned, and being simple inconstruction, can be made cheaply and durably. Any part or parts can bereplaced without renewing the whole trap. The entrance being wide andcomparatively low at the end, is adapted to fit under radiators and incorners where the insects are likely to be.

In operation, the trap is placed with the entrance on the floor, wherethe cock-roach, or other insect, scents the bait at the mouth. Theinsect crawls up the entrance scenting first the bait under foot, andthen that suspended at E, crawling toward this latter bait, he fallsinto the trap. No resetting or new bait is required, for the nextinsect. The trap is always in working order.

It is to be understood that changes may be made in this trap withoutdeparting from the spirit of my invention. The entrance may be maderound, square, triangularshaped, or any convenient shape in crosssection; and one or more entrances may be used. In the drawings I haveshown a sponge or other absorbent material that may be saturated withliquid bait suspended at E. This baiting means may be suspended by awire from the cover, and in smalljraps is preferably hung slightly toone side, so that the insect could not possibly reach the bait from theend of the tube. In the drawings, it is shown hung to one side.
